Spamel smart switch OP1-W01-A-M automatic 1 NO, 2 changeover contacts with hammer actuator

Spamel OP1-W01-A-M is an automatic pushbutton/switch designed for control and signaling applications. The device integrates a hammer-style actuator that provides a tactile, momentary action. It combines one normally open (NO) contact and two changeover (SPDT) contacts to accommodate multiple control circuits in a single compact unit. The switch is intended for use in door entry systems, alarm circuits and simple machine-control or interlock functions where a short, reliable pulse is required.

Advantages

The hammer actuator delivers a clear mechanical response and consistent contact action suitable for repeated momentary operation. The combination of one NO and two SPDT contacts enables flexible wiring options for simultaneous signaling and control functions without additional modules. The compact design simplifies installation into control panels or mounting boxes while maintaining isolation between circuits and ensuring straightforward maintenance.

Suitable for

• Door entry and intercom systems requiring momentary call or release signals
• Alarm and signaling circuits where a short, reliable pulse is needed
• Machine control applications for start/stop or safety interlocks
• Control panels where multiple contact functions are required in a single device

Key specifications

• Actuator type: hammer-style (momentary action)
• Contact configuration: 1 normally open (NO) + 2 changeover (SPDT) contacts
• Intended operation: momentary/pushbutton switching
• Application environments: electrical installations for signaling and control
• Mounting: panel or mounting box integration (compact footprint)

How to use

Mount the Spamel OP1-W01-A-M in the appropriate panel cut-out or enclosure following local electrical installation regulations. Connect the incoming and outgoing conductors to the corresponding contact terminals according to the required function: use the NO contact for single-pole momentary outputs and the SPDT contacts for changeover or alternate circuits. Ensure supply and load ratings are compatible with the control circuits in which the switch is installed. After wiring, verify mechanical movement of the hammer actuator and perform an electrical test to confirm contact operation before placing the system into regular use.

Usage recommendations

Use the device in dry, protected indoor environments unless additional protective measures are provided. Periodically inspect contact terminals for secure connections and signs of wear; replace the unit if contact reliability degrades. When integrating into safety-related circuits, follow applicable standards and use appropriate monitoring or redundancy as required.
