Product Description

When hermetically sealed switches (metal-to-metal and glass-to-metal sealing) are a requirement for demanding applications,

Honeywell MICRO SWITCH™ HS Series premium large basic switches fulfill the need. The HS Series design incorporates a

MIL-PRF-8805 symbol 5 hermetic seal to comply with hermetic seal requirements. HS Series switches are capable of controlling

logic level/low energy applications, as well as power-duty switching to solve many applications. With a compact package size, HS Series switches have overall dimensions of 1.96 inch length, 1.18 inch height, and 0.67 inch wide and are suitable for applications where space is limited.
 

In addition to MIL-PRF-8805 qualified HS Series switches, UL and CSA certified HS Series basic switches are available for a wide variety of applications.
