## Long description

Timex TOPAZ WP-7T/S is a momentary push-button smart switch intended for doorbell and other short-contact applications. The WP-7T/S BI model provides a normally open contact that closes only while the button is pressed, allowing precise, user-initiated triggering of chimes, intercoms, automation inputs or other low-voltage control circuits. Designed for integration into smart home and building control systems, the device offers a straightforward mechanical interface for systems that require a transient pulse rather than a maintained switch state.
Advantages
This momentary push-button delivers reliable short-contact switching with a normally open contact configuration, minimizing wiring complexity for low-voltage control tasks. Its compact form factor and mechanical operation make it durable and simple to integrate with existing doorbell, intercom and automation inputs. The device provides predictable, instantaneous response with each press, suitable for installations where brief pulses are required to trigger relays, chimes or logic inputs in smart controllers.
Suitable for
 Doorbell button replacements and new doorbell installations
 Intercom call button inputs
 Triggering automation inputs and control panels that accept momentary pulses
 Low-voltage control circuits requiring a normally open, momentary contact
Key specifications
 Contact type: normally open, momentary (push-to-make)
 Intended use: doorbell and short-contact control applications
 Operation: mechanical push-button with transient contact closure while pressed
 Electrical environment: designed for low-voltage control circuits
 Mounting: panel or wall-mounted push-button form factor suitable for integration into switch plates or housings
How to use
Connect the device in series with the low-voltage control circuit or input you intend to operate, observing polarity and local wiring regulations where applicable. Install the push-button in a suitable panel, wall box or doorframe location so the actuator is accessible to users. When pressed, the normally open contact closes and sends a transient signal to the connected chime, intercom or automation input; release returns the contact to the open state. Test the function after wiring to confirm the momentary action triggers the intended device or control input.
Usage recommendations
Use the switch only within low-voltage control systems and avoid exposing it to moisture or direct water ingress unless the installation location and housing provide appropriate protection. For reliable long-term operation, ensure connections are secure and matched to the control device's input specifications.
