Compact and highly environmentally resistant microswitch that can be mounted in places where it could not be placed before
Miniaturization has made it easy to mount the switch in narrow spaces, where it could not previously be mounted, or in applications that require a large number of detections and environmental performance such as water and dust resistance.
Application examples: Smart meters (electric power), gas meters, quick chargers (for electric vehicles), security equipment, welding machines, packaging machines, food and beverage related equipment, etc.
![Ultra compact: Industry's smallest*1 class (W 8.3 x D 5.3 x H 6.5 mm), Excellent environmental resistance: IP67 environmental resistance (operating temperature range: -40°C to +85°C), Excellent reliability: High reliability with slide contact structure](/eu-en/sites/components.omron.com.eu/files/2022-07/onboard_250_2_02_en.png)
![Selectable from 2 types of mounting structures, 4 types of terminal specifications, with or without levers](/eu-en/sites/components.omron.com.eu/files/2022-07/onboard_250_2_03_en.png)
