The PikoButton 50 is a durable switch from Finland.
When we ran across these switches, we were immediately impressed by their thoughtful design. To say they're shock and cold resistant is not doing them justice - we've stomped on them and they still keep working.
The light activation model is sensitive to only 75g of pressure.
Two other activation types are also available, in all colours -- regular (125g) and stiff (250 g).
Also available in an immersible water resistant version and 30 mm diameter versions.
Features:
Dimensions: 13mm x 50 mm.
Sensitive response with just 0.8mm activation travel.
Auditory and tactile feedback.
Supplied with a standard 3.5mm jack and 1.5m cable.
