Camden Door Controls CM-400 Series mushroom push switches are medium-duty push-button controls available in red, blue, or green, with a 1 5/8" (40mm) diameter free-spinning button for protection against vandalism. They are supplied with an industrial grade stainless steel faceplate in one gang or two gang widths, and are UL/CSA approved, rated 6 amps @ 30V DC.

Product specifications
Low-voltage wiring Required
BasisStructured, independently qualified product connection evidence
PreparationProvide the mullion mounting arrangement for this model and allow clearance behind its faceplate for the contact assembly and wiring. Secure the faceplate with its supplied mounting hardware. Insert wiring into the top and bottom contact-block terminals and tighten the screw terminals. Follow the numbered terminals and verify the installed contact blocks before commissioning; do not identify contact operation from the mushroom button color.
ElectricalFor a selected low-voltage controlled circuit, this momentary model provides normally open and normally closed contact operation. Each used SPST contact connects through two external circuit conductors. Select the NO contact, NC contact, or both functions to match the controlled equipment; keep their terminal assignments distinct. Follow the numbered contact-block terminals. Verify the actual contact block and supplied spade lead set against its terminal markings. Factory spade leads do not establish field cable-run count. Physical cable-run quantity, field cable type, gauge and shielding require the connected-device instructions and site routing. Contact-load ratings describe the switched circuit, not a separate switch power-supply requirement.
Preparation requiredYes
Electrical wiring requiredYes
Conditional connectionsSelected normally open switch-contact circuit: cable runs quantity unspecified; 2 conductor(s); wire type not documented; size unspecified; shielding unspecified; rating Field cable type, gauge, shielding and physical run quantity unspecified; select for controlled device and site.; endpoints Selected low-voltage controlled equipment to CM-420N normally open contact terminals; when Installation configuration is Standard CM-420N; use this normally open contact for the selected controlled function. Two conductors serve this contact; factory spade leads and physical cable-run quantity are separate.; Selected normally closed switch-contact circuit: cable runs quantity unspecified; 2 conductor(s); wire type not documented; size unspecified; shielding unspecified; rating Field cable type, gauge, shielding and physical run quantity unspecified; select for controlled device and site.; endpoints Selected low-voltage controlled equipment to CM-420N normally closed contact terminals; when Installation configuration is Standard CM-420N; use this normally closed contact for the selected controlled function. Two conductors serve this contact; factory spade leads and physical cable-run quantity are separate.
