Miniature vertical side-actuated detection switches ideal for safety applications

C&K’s FDSD and FDSE series are micro-mini, side-actuated detection switches suitable for applications which require vertical side detection. They are particularly useful for safety control applications, and for medical and consumer devices.

An example of the use of these switches is in inhalers, where they detect the presence of a cartridge, activating the drug delivery process and confirming the dose has been dispensed.

The FDSD and FDSE parts are available now in production volume from Future Electronics. Serving customers from 48 branches in the Europe, Middle East and Africa region, including six branches in Germany, Future Electronics offers the industry’s largest available-to-buy inventory of electronics components – including electro-mechanical components such as the FDSD and FDSE switches.

The FDSD series of micro-mini side-actuated detection switches are available in a small package size of 4.2mm x 3.6mm x 1.2mm, with optional flat or bent terminals for simple PCB mounting. The beryllium copper contacts have a resistance of less than 1Ω and are rated for 10mA current at 5V DC and a lifetime of 50,000 operations.

The detection switch requires a maximum actuation force of 40gf and can travel through an angle of 60° or a distance of 3.05mm.

Features:

  • Single-pole single-throw configuration
  • FDSD switches are normally open
  • FDSE switches are normally closed
  • 100MΩ minimum insulation resistance
  • 100V AC/1 minute dielectric strength

The FDSE range adds an angled capability to the range. Featuring the same package size and lifetime rating, the FDSE switches have an electrical rating of 1mA at 5V DC. The angled detection switch requires a maximum actuation force of 35gf and can travel through an angle of 60° or a distance of 3.14mm.
