Value Collection RCM-403 Limit Switch Spdt Nc Coil Spring

Product Description

The VALUE COLLECTION RCM-403 is a general purpose limit switch designed for position sensing and machine control applications. It features a single-pole double-throw (SPDT) contact form with a normally closed (NC) configuration and a coil spring actuator mounted at the top of the unit. The body is constructed from a combination of metal and plastic for durability in light industrial environments. Terminal connections are made via top-mounted screw terminals, simplifying field wiring. This switch is UL Listed and weighs 0.3 pounds, making it a compact and code-compliant solution for electricians and maintenance technicians working on automated equipment and control panels.

The RCM-403 is suited for residential and commercial light industrial applications where mechanical position detection is required. Typical uses include conveyor systems, machine guarding interlocks, door position sensing, and other electromechanical control circuits. The coil spring actuator provides reliable return action after contact actuation. This switch is packaged as a single unit and is appropriate for both new installations and direct replacement of worn or failed limit switches in existing control systems.

Key Features

• SPDT contact form with normally closed (NC) configuration for fail-safe circuit design
• Coil spring actuator with top mounting location for straightforward mechanical alignment
• Screw terminal connections for secure, tool-based field wiring
• Metal and plastic body construction for lightweight durability
• UL Listed for use in code-compliant electrical installations
• Compact form factor at 0.3 pounds for easy panel and machine integration

Compatibility

Designed as a general purpose replacement or new-installation limit switch for light industrial electromechanical control circuits requiring SPDT NC contact configuration with a coil spring actuator.

Installation Notes

Installation should be performed by a qualified electrician or maintenance technician in accordance with the National Electrical Code (NEC). De-energize all power to the circuit before mounting the switch or making terminal connections. Screw terminals should be tightened with a flathead screwdriver to ensure secure wire retention and prevent intermittent contact. Verify actuator alignment with the mechanical trip point before returning the system to service.
