S880 – Microswitch with positive opening operation

The Schaltbau S880 microswitch is recommended wherever reliable switching functions need to be implemented within a limited installation space. The V4 switch with positive opening operation has the same features as the large snap-action switches, but is only 6 mm wide. However, while these were for the most part developed for special applications, the S880 is designed for the mass production of devices and machines in which safety functions need to be implemented.

Features and technology

The technical principles of Schaltbau’s snap-action switches in designs A and F were transferred to the dimensions of a microswitch:

S880 = V4 snap-action switch with positive opening operation

  • Snap mechanism with high shock and vibration resistance
  • Self-cleaning contacts
  • Long mechanical working life
  • Designed in protection types IP 40, 60 and 67
  • Can be used in various applications due to additional actuator



Applications of the microswitch

The S880 can be used wherever switching needs to be performed safely within a small space. Its low price makes it ideal for mass-produced applications in which cost pressure is a major factor.

A selection of applications:

  • Safety and limit switches in compact devices for medical technology
  • Operating tables
  • Machine, system and process control systems with limited installation space
  • Belt off-track switches
  • Universal joint shafts
  • Safety locking systems, safety hinges
  • Electrically driven doors, gates and awnings
  • Compact operating devices with joystick function
  • Hand-held chainsaws and other hand-operated, motorised tools
