Product Description

Amprobe's Remcon relays feature a standard 3-wire relay with built-in transformer and stripped leads. Designed for the low voltage lighting systems common in homes built in the 1950s, 1960s and 1970s. These new solid state Remcon low voltage relays replace the R-115 and old solenoid coil type Pyramid relays and can be used in all present applications, plus many new applications. (The old Remcon R115 was only rated to 5 amps, and used 750 mA of AC control current.)


  • Fluke Amprobe low voltage relay switch - 100% solid state, 6.5 amp, 120 volt, 60 Hz
  • built in transformer, with no step down transformers necessary; momentary contact closure of control wires turns AC power ON or OFF
  • AC voltage from 105 to 125 VAC.
  • 2.5" wide by 1.125" deep by 1.83" high
  • AC current rating: resistive, tungsten or ballast load up to 6.5 amp (1/4 HP max. motor load at 120V) maximum
  • control switch closure time: 5 milliseconds minimum
  • safe control switching: 10.0 VDC max. isolated from AC line and 10 miliamps max
  • ambient operating temperature: 40 degrees celsius max for full rated output current
  • limited lifetime warranty
  • UL listed
  • made in China
  • switches AC power ON and OFF using low voltage control circuit
  • replaces old Remco or Pyramid Electric relays 

IMPORTANT: If there is more than one relay on a circuit, the relays must be the same type, i.e. all R115 (mechanical, old style) or all R115S (solid state, as shown). They cannot be intermixed because of the difference in control currents. The old mechanical relays were a different shape - a cylinder on rectangular black base - and might have either Remcon or Pyramid brand on them.)

Multiple relays can be controlled by a single switch. A single relay also can be controlled by multiple switches. This quality megohmmeter has a solid range of features which were designed to meet most insulation test applications.

To install in a metal electrical box, just insert through the knock-out opening hole. For better heat dissipation, we recommend installing with included mounting nut. Must be securely installed in metal boxes only (not in plastic electrical boxes) because solid state switches generate heat.

Includes wiring diagram along with hook-up directions for replacing the older Remcon R-115 (electromagnetic switch relay). A significant time and cost savings can be achieved by using light #22 cable to control relay instead of Romex or armored cable.

Remcon switchplates were typically installed horizontally (sideways) with the switches rocking up and down to turn lights on/off. The curved, flared Remco switches were pinched in and narrower at the middle and wider and taller at the top with a small dot (red for pilot lights) at the center. (Original type of Remcon mounting frames, ivory curvy rocker switches and rounded or oval wall plate covers are no longer in production. If you are looking for a replacement for Amprobe's discontinued Remcon low voltage switches, we recommend Touch-Plate Lighting Control switches for a safe alternative.)

New Applications for R115S Amprobe Low Voltage Relays

  • Industrial Control Applications
  • Higher current applications. (Up to 6.5 Amps, 1/4 HP)
  • Where isolated low voltage is need for safety reasons.
  • Long-distance remote operation with twisted pair wire.
  • Computer control applications.
  • Alarms.
  • Plant process controls.
  • Applications where a U.L. Listed device is required.
  • Reduce control wiring costs and electrical interference.
  • Hostile or hazardous environments.
  • Economically meet building codes in new installations.

Warranty Information

Q. If I am replacing my old Remcon switches with new Touch Plate light switches, do I have to use Touch-Plate relays with them?
A. NO. Always use Remcon relay switches in your Pyramid or Remcon lighting system. Touchplate relays will not work in your Remcon setup.

Q. What does the loud buzzing sound from my relay mean?
A. If you hear a noisy buzzing sound coming from your relay, this can mean 1 of 2 things: the relay is bad and you need a new one, or the switch is bad and you need a new one. To test which component is bad, you need to get a working switch that is installed somewhere else in your home. Wire it in place of the switch that is connected to the loud buzzing relay. If the relay continues to buzz, you know the relay is bad. If the relay stops buzzing, you know the switch is bad.
