Alarm Controls Corporation KR-2 Latching Key Switch 2 N/o

Product Description

The Alarm Controls Corporation KR-2 is a single-gang, stainless steel latching key switch with two normally open (N/O) contacts. Designed for access control and security applications, it provides a durable, corrosion-resistant switching point that remains latched in position until manually returned. The KR-2 is installed by licensed electricians and security system integrators in low-voltage control circuits where a keyed, tamper-resistant input is required. Its plate-style form factor fits standard single-gang electrical boxes, making it straightforward to integrate into new construction or retrofit projects.

The KR-2 is suited for commercial and light industrial access control installations, including entry points, elevator controls, door release circuits, and security panel inputs. The two N/O contact outputs allow it to interface with a wide range of control systems, including door strikes, magnetic locks, alarm panels, and relay modules. Its stainless steel faceplate holds up in high-traffic or corrosive environments where standard finishes may degrade over time.

Key Features

• Latching key switch action holds position until key is rotated back
• Two normally open (N/O) contacts for dual-circuit switching capability
• Stainless steel faceplate resists corrosion in demanding environments
• Single-gang plate format mounts to standard electrical boxes
• Keyed operation prevents unauthorized switching

Compatibility

Designed as an OEM-style replacement or new-installation component for single-gang access control and exit device switch circuits in commercial and light industrial security systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified security systems integrator. Shut off all power to the control circuit before wiring the switch contacts. Follow applicable NEC guidelines for low-voltage wiring and enclosure fill. Verify contact ratings against the connected load before energizing the circuit.
