George Risk Industries 4613 Spdt Mini Curtain Door Switch

Product Description

The George Risk Industries 4613 is a single-pole double-throw (SPDT) mini curtain door switch designed for special application contact sensing. This compact switch detects the open or closed position of curtain-style doors and triggers control circuit responses accordingly. It is suited for low-voltage signaling and monitoring circuits where a reliable mechanical contact is required. Licensed electricians and security or access control technicians are the primary installers. The SPDT configuration provides both a normally open and normally closed output, giving installers flexibility when wiring into monitoring panels or control logic.

This switch is applied in specialized door and access point sensing scenarios, particularly where curtain-style or flexible door panels are used. Typical installations include industrial enclosures, commercial partitions, and specialty access panels that require position feedback to a control system. It is sold as a single unit and intended for integration into custom control or alarm circuits.

Key Features

• SPDT contact configuration provides both normally open and normally closed outputs in a single device
• Compact mini form factor suits tight mounting locations on curtain door frames or tracks
• Designed for special application contact sensing beyond standard door and window use
• Single-unit packaging allows targeted replacement or new installation without over-ordering

Compatibility

Designed as an OEM-style replacement or new-installation component for special application curtain door contact sensing circuits requiring an SPDT mini switch.

Installation Notes

Installation should be performed by a qualified electrician or licensed low-voltage technician. De-energize the control circuit completely before wiring or replacing this switch. Secure mounting to the door frame or track per the manufacturer data sheet to ensure consistent actuation. Work should comply with applicable NEC requirements for control and signal wiring.
