Sdc D15-2 Momentary Spdt Desk Switch Button

Product Description

The SDC - SECURITY DOOR CONTROLS D15-2 is a momentary single-pole double-throw (SPDT) desk-mounted switch button designed for access control and door release applications. This type of switch provides a brief contact closure or transfer when the button is pressed and released, making it suitable for triggering electric strikes, magnetic locks, and other access control hardware. It is intended for use at a stationary desk or workstation and is typically installed by security system technicians or licensed electricians working on low-voltage access control circuits.

The D15-2 is used in commercial and institutional settings where a desk operator needs local control over door release or locking hardware. Typical installations include reception desks, security stations, and administrative workstations where a single operator must control entry points. The momentary action ensures the circuit returns to its normal state as soon as the button is released, which is a standard requirement for access control relay logic.

Key Features

• Momentary action returns circuit to normal state upon button release
• SPDT contact configuration supports both normally open and normally closed wiring
• Desk-mount form factor suited for stationary operator stations
• Compatible with low-voltage access control systems including electric strikes and magnetic locks
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style replacement or addition for desk-mount momentary switch applications in commercial access control and door release systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified access control technician familiar with low-voltage wiring practices and applicable codes. De-energize the access control panel and any associated door hardware before making or breaking wiring connections. Follow NEC guidelines for low-voltage control wiring, and verify that the switch contact rating is compatible with the load it will switch before placing the circuit in service.
