## Long description

Promet LM-1 is a miniature switch designed for compact electrical control in panels, enclosures and small machinery. Rated for 400 V and 16 A with a single pole / single throw contact arrangement, the LM-1 offers straightforward on/off switching where basic dust protection is acceptable. The IP40 protection level makes it suitable for indoor installations and protected electrical cabinets where exposure to large particulates is limited.

The LM-1 miniature switch combines a small footprint with industry-standard electrical ratings, allowing integration into control panels and appliance interfaces without significant space or design changes. Its single-pole contact provides simple and reliable switching behaviour under the specified voltage and current. The device’s construction supports panel or enclosure mounting and offers durable performance for routine switching tasks in residential and light industrial environments.
Suitable for
Control panels and distribution boards with limited installation space

How to use
Install the switch in a prepared panel cut-out or enclosure opening following the mounting provisions of the control panel. Ensure all power is disconnected before making electrical connections. Connect conductors to the switch terminals in accordance with local wiring regulations and the intended circuit diagram, observing correct polarity and secure terminal fastening.

Usage recommendations
Use the Promet LM-1 where compact, single-pole switching is required and indoor conditions do not demand high ingress protection. Avoid outdoor exposure or locations with fine dust, moisture or spray.
