The Capacitive touch sensors from iFm is a wall fitting sensor that features a large extent of suppression against unnecessary objects, liquids and thick portions of ice. Furthermore, the capacitive touch sensors has the ability to work through glass and even through a covered hand. Compared to mechanical switches, the capacitive touch sensor is a wear and tear free and does not require force to operate. For the Capacitive touch sensors it is best use in the industry for operation of machines, and to mobile applications for button sensors.
