The EFM series have been tested and approved to meet the requirements of the Low Voltage directive and positive opening safety contacts per IEC/EN 60947-5-1-3.
Typical applications for these switches would use the roller plunger in conjunction with cams on doors with hinges .
A rang of panel mounting or top mounting versions are also available to ensure that the switch can be simply installed in small space or difficult mounting.
