Camden Door Controls CM-300/310 Series LED Illuminated Exit Switches are economical illuminated exit controls with 1/2" x 3/4" buttons available in red or green, supplied with a stainless steel faceplate in 1 3/4" or 2 3/4" widths. The SPDT momentary switch is UL/CSA approved and the LED bulb runs on 12V or 24V DC. CM-310EE adds an integrated 30-second timer with double-break circuitry for magnetic lock applications.
| Operating voltage | 12 or 24 V DC |
|---|---|
| Time delay | 30 seconds |
| Contact rating | 4 amps @ 30 VDC |
| Switch life | 15,000 hrs. @ rated capacity (bulb life) |
| Mounting | 2 x #6-32 machine screws |
| Dimensions | 2.75" W x 4.5" H x 1 5/16" (70mm x 114mm x 33mm) |
| Low-voltage wiring | Required |
| Basis | Structured, independently qualified product connection evidence |
| Preparation | Provide the single-gang box mounting arrangement. Tuck wiring into the box and fasten the plate using the supplied screws. Select the mounting substrate and verify clearance for the switch and soldered leads. Select the intended button color for the blank-faceplate base model before ordering. |
| Electrical | This exact model has momentary SPDT contacts. For the selected low-voltage controlled circuit, connect green common and blue NO for normally open operation, or green common and yellow NC for normally closed operation: two external circuit conductors for either choice. Using common and both throws requires three external switch conductors. The LED has a separate two-conductor supply: red positive and black negative. For 12 VDC, the manual instructs removal of the inline resistor on the black wire only; for 24 VDC, leave it in place. Verify the delivered lead assembly and chosen supply before connecting. The supplied soldered leads are distinct from field cable runs. Field cable type, gauge, shielding and physical cable quantities depend on the controlled equipment and site routing. |
