Safety push button Spamel SP22-B-02/OBC/B — red, 2R contact, nickel-plated ring, housed OBC

The Spamel safety push button SP22-B-02/OBC/B is a red emergency/control actuator designed for integration into industrial control panels and safety circuits. This unit provides two R-type (2R) mechanical contacts and a nickel-plated metal ring mounted in an OBC-style housing, offering a clear visual signal and a robust interface for machine stop and control applications.

Advantages

The red actuator ensures immediate visual recognition for emergency stop or critical control use. The mechanical 2R contact configuration supports reliable circuit opening and closing for safety interlocks and control logic. A nickel-plated ring increases surface durability and corrosion resistance while maintaining a professional metal appearance. The OBC housing form factor simplifies panel mounting and protects the contact assembly from accidental contact and dust.

Suitable for

• Emergency stop buttons on machinery control panels
• Operator control stations and push-button consoles
• Safety interlock and e-stop circuits in production lines
• Retrofit or new installations in industrial enclosures

Key specifications

• Actuator color: red for emergency/control signaling
• Contact configuration: two R-type (2R) mechanical contacts
• Ring finish: nickel-plated metal ring for enhanced durability
• Housing style: OBC panel-mounted housing
• Mounting: standard panel cut-out compatible with OBC form factor

How to use

Install the push button into a compatible panel cut-out and secure according to the panel manufacturer’s instructions. Connect the two R-type mechanical contacts into the control or safety circuit following electrical schematics and applicable safety standards. Use the red actuator position as the primary visual cue for emergency or stop functions. Periodically inspect the metal ring and housing for signs of wear or corrosion and ensure contact terminals remain tight to maintain reliable operation.

Usage recommendations

For safety applications, verify compatibility with your machine’s safety category and applicable local regulations before installation. Test the switch function after wiring and during routine maintenance to confirm proper operation of the safety circuit.
