## Summary description

Surface-mounted ELEKTROPLAST HERMES 0337-09 doorbell switch in black. Designed as a momentary (normally open) press-to-make contact for use with residential or commercial doorbell circuits.

## Long description

Surface-mounted ELEKTROPLAST HERMES 0337-09 doorbell switch in black is a compact, press-to-make momentary switch designed for doorbell and signaling circuits in residential and commercial installations. The unit provides a wall-mounted control point that closes the circuit only while the button is pressed, making it suitable for standard bell transformers, chimes and low-voltage signaling systems. With a slim profile and simple mounting arrangement, the switch is intended for surface installation on junction boxes or directly onto flat wall surfaces where recessed wiring is not available.
Advantages
The switch offers a straightforward mechanical design with a tactile push-button action and normally open contact suitable for momentary signaling. Its surface-mounted form factor simplifies installation, eliminating the need for recessed boxes in many retrofit situations. The black finish provides a discreet appearance that blends with contemporary interiors and hides fingerprints and minor scuffs. The device is compatible with common low-voltage bell wiring and is constructed to provide reliable switching for frequent use.
Suitable for
 Residential doorbell circuits and home entrance chimes
 Small commercial premises requiring a simple call or alert button
 Retrofit installations where surface mounting is preferred or necessary
 Low-voltage signaling systems and temporary access control buttons
Key specifications
 Switch type: Momentary (normally open) press contact
 Mounting: Surface-mounted for wall or junction box installation
 Finish: Black
 Application: Doorbell and low-voltage signaling circuits
 Actuation: Manual push-button
 Compatibility: Standard bell/chime wiring and low-voltage transformers
How to use
Mount the switch on a suitable surface or on a compatible surface junction box using the provided screw locations. Connect the two bell circuit wires to the switch terminals according to the existing doorbell wiring: one terminal to the transformer/chime circuit and the other to the bell input. Ensure power to the circuit is turned off before wiring. After secure mounting and wiring, restore power and press the button to test operation; the circuit should close only while the button is depressed.
Usage recommendations
Use the switch only with compatible low-voltage doorbell transformers and chime units. Avoid exposure to direct moisture or outdoor weather unless installed within a protected enclosure. For reliable operation, verify wiring polarity and secure terminal connections; consult a qualified electrician if unsure about installation or local electrical regulations.
