Timex WP-7 Op BI momentary push button switch Opal white — wall-mounted smart switch accessory

Timex WP-7 Op BI is a momentary (normally open) push-button switch in Opal white finish, designed as a wall-mounted control accessory for lighting and automation systems that accept a dry-contact or momentary trigger. Its compact housing and simple mechanical action make it suitable for retrofit installations, manual control points, and integration with smart control panels. The device provides a discrete, tactile input without built-in electronics, allowing compatibility with a wide range of controllers and relays.

Advantages

The Timex WP-7 Op BI offers a low-profile design and a neutral opal white appearance that blends with standard wall plates. As a momentary, normally open push-button, it provides reliable mechanical switching with minimal latency and a long service life under normal use. Because it is a dry-contact input device, it is broadly compatible with automation systems and does not require dedicated power or proprietary signaling to operate.

Suitable for

• Manual control points for indoor lighting circuits
• Input trigger for home automation controllers and relays
• Retrofit or new installations in residential and small commercial spaces
• Momentary control for door entry systems or gate openers that accept dry-contact inputs

Key specifications

• Switch type: Momentary (normally open) push-button
• Finish: Opal white
• Mounting: Wall-mounted, compact form factor for retrofit applications
• Contact type: Dry-contact (mechanical), suitable for low-voltage triggering circuits
• Typical use: Input for lighting, automation controllers, relays, and similar devices

How to use

Install the Timex WP-7 Op BI into a standard wall box or compatible mounting plate following local electrical regulations. Connect the switch contacts to the input terminals of the target controller, relay, or panel that accepts a dry-contact or momentary input. The switch does not require a power supply; it acts as a mechanical closure between its terminals when pressed and returns to open when released. Verify correct polarity and wiring with the controller manufacturer’s wiring diagram before energizing the system.

Usage recommendations

Use the WP-7 Op BI for low-voltage control circuits and ensure the connected controller supports normally open momentary inputs. Avoid exposure to excessive moisture or direct water contact; install in indoor locations or suitably protected enclosures. For long-term reliable operation, mount the switch securely and avoid mechanical stress on wiring during installation.
