S880 W2G6 a
Microswitch S880 with pushbutton and soldering lugs. IP67 design (contact area).
The housing of this V4 snap-action switch only measures 20 × 9.3 × 6.6 millimetres. Yet the same switch technology as the A-design S870 is achieved in the S880 subminiature switch, including positive opening. This microswitch is therefore recommended for all applications in which secure switch functions have to be achieved in small installation areas.
The user can configure the optimal version from a wide range of various actuators and connections according to the required protection class and the installation situation..
Features
Changeover contact in miniature design; dimensions 20 x 9.3 x 6.6 mm (L x H x W)
This is the maximum dimensions of the housing. The dimensions of the actuator and of the connections must be added. For all dimensions and drawings please refer to the following product catalogue:
V4 subminiature switches with dimensions pursuant to DIN 41636, design B. Changeover contact with single break.
Break contact with positive opening
If the break contacts fuse in the event of a short circuit, the catch spring can no longer open. It is nevertheless opened reliably via the lever of the positive opening. This is a positive opening as outlined in DIN EN 60947-5-1, annex K.
Self-cleaning contacts
The moving contact rubs against the fixed contact during every actuation. This removes corrosion and combustion residue and reduces contact resistance.
Reliable switching of low currents
With self-cleaning silver contacts, small currents can be connected reliably and frequently. In chemically aggressive environments and with low switching frequencies, we recommend gold contacts.
Shock resistance 50 g, vibration resistance 50 g
The switch mechanism of this microswitch has been designed to be especially robust. Catch springs and return springs are designed so that the switching process works reliably even in the event of shocks and vibrations.
