Suburban 233111 DEL Water Heater ON/OFF Wall Switch
This wall-mounted ON/OFF switch is engineered for Suburban DEL model tank water heaters and direct-fit upgrades. The product is presented as an OEM-style control intended for interior wall mounting and straightforward operation.
- Application: Intended for RV and stationary tank water heater control panels; applicable where a compact wall-mounted toggle is needed.
- Construction: Described as durable with a sleek black finish that integrates with interior panels.
- Relevance To Railroad Switch Heaters: Useful as a rugged on/off control for mounted heater control boxes where a wall or panel-mounted toggle is required for field-accessible heater circuits.
28785 On/Off Switch For Mr Heater
This item is a replacement On/Off switch listed as Part #28785 for Heat Star and Mr Heater kerosene forced air heaters. It is specified for direct heater replacement and service purposes.
- Fitment: Specified for several heater models used in portable and forced-air heating units.
- Function: Basic on/off function with compatibility notes for common heater brands and part numbers.
- Relevance To Railroad Switch Heaters: Suitable as a replacement control switch inside a turnout heater assembly or in portable forced-air heater systems used for switch heating during maintenance operations.
2 Pack 120927-24 Lighted Rocker Switch For Electric Heaters

These lighted rocker switches are specified with a robust AC current rating and common form factor for electric heater and fireplace replacement. They are marketed as compatible with a range of electric appliance models.
- Electrical Rating: Rated for high-current AC applications; designed to meet common heater load requirements where a lighted indicator is beneficial.
- Compatibility: Replaces OEM switches in many electric fireplaces and heaters, with mounting and prong styles matching specified appliance models.
- Relevance To Railroad Switch Heaters: Applicable for use in fixed-box assemblies controlling electric heating elements on track switches, especially where a visible illuminated indicator is required for operational confirmation.
DC Motor Speed Controller Universal DC 12V 24V 10A
This stepless DC speed regulator controls motor RPM and is rated for 10A continuous load at 12V or 24V systems. It is commonly used to control fans and small DC motors in heater systems.
- Voltage Range: Works on both 12V and 24V DC systems, making it adaptable to battery or control-panel power commonly found in field heater setups.
- Control Type: Stepless rotary knob allows fine adjustment of fan speed, supporting smoother modulation than fixed-step selectors.
- Relevance To Railroad Switch Heaters: Useful for controlling blower fans or circulators in turnout heater assemblies where variable airflow improves heat distribution and energy efficiency.
GZS-15 Rotary 4 Position Fan Speed Selector Switch
The GZS-15 rotary selector is a multi-position switch designed for fan speed selection on small heaters and radiators. It offers a rated amperage suitable for many low-voltage heater fans and is made with flame-retardant materials.
- Positions: Multi-position design provides discrete speed steps useful for step-wise control strategies.
- Ratings & Materials: Specified current/voltage ratings and high-temperature-resistant materials for safety in heater environments.
- Relevance To Railroad Switch Heaters: Applicable when discrete fan speeds are preferred, or when a simple, durable selector is required for turnout heater blowers or auxiliary circulation devices.
Buying Guide For Railroad Switch Heater Controls
Selecting the right control switch or controller for a railroad switch heater depends on the heater type, power source, environmental conditions, and maintenance practices. Below are the primary considerations.

Heater Type And Load Requirements
Confirm whether the turnout heater is electric resistance, forced-air, or uses an auxiliary fan. Match switch ratings to the heater’s full-load current and inrush current. For resistive elements, choose switches rated for the element’s steady-state amperage; for blower motors allow for higher inrush currents.
Voltage And System Compatibility
Rail turnout systems may run on 12V, 24V DC, or 120/240V AC. Choose switches and controllers rated and designed for the system voltage to avoid overheating and unreliable operation. DC speed controllers are relevant for battery-backed or low-voltage blower circuits.
Control Type: On/Off, Step, Or Stepless
On/Off switches provide simple control and are often used for manual or remote-enabled heaters. Multi-position rotary selectors offer discrete speed levels for fans. Stepless PWM or electronic controllers give precise modulation and energy savings. Pick the control method that matches operational requirements (manual operation vs automation).
Environmental And Mounting Considerations
Switches mounted on outdoor cabinets or exposed junction boxes should be installed inside rated enclosures or use switches with suitable ingress protection. Choose components with flame-retardant housings and durability for temperature variation.
Indicator Lights And Operator Feedback
Lighted rockers or illuminated switches provide clear visual confirmation of heater status, helpful during low-light operations. Consider illuminated controls for field serviceability and quick diagnostics.
Durability, Replacement Fitment, And Serviceability
For railroad applications, choose replacements that meet OEM fitment where possible, and components with known part numbers for easier field servicing. Replace failed controls with same-type rated components to preserve system safety margins.
Power Distribution And Circuit Protection
Ensure the switch or controller is paired with appropriate fusing or circuit breakers sized for the heater load and inrush. Use wiring with proper gauge for continuous current and protect control panels from overcurrent events.
Control Integration And Automation
If integrating with thermostats, remote monitoring, or trackside control systems, verify the switch or controller supports remote actuation or can be adapted using relays or contactors. Electronic speed controllers may require additional isolation when interfacing with control circuitry.
Tips for Getting the Best HVAC Prices

Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Comparison Perspectives
- Manual Simplicity: Basic on/off switches and lighted rockers provide the simplest repair and operation for field crews.
- Variable Control: DC stepless controllers and rotary selectors enable better heat distribution and energy control for blower-driven systems.
- High-Current AC Heating: Use heavy-duty lighted rockers or OEM-rated replacement switches for 120/240V elements.
- Serviceability: Replacement part-numbered switches (OEM part numbers) tend to reduce installation time and improve reliability in maintenance cycles.
