Omnibearing tact switch

Abstract

The invention relates to an omnibearing tact switch comprising an outer wall sleeve and an inner wall sleeve, wherein the outer wall sleeve is arranged outside the inner wall sleeve, a silica gel gasket is embedded between the outer wall sleeve and the inner wall sleeve, and a positioning rubber ring is embedded between the bottom of the outer wall sleeve and the bottom of the inner wall sleeve. The pressed sensing type switch is characterized in that an LED switch does not need to be pressed by fingers all the times, which more conforms to the writing custom of an operator; and because the switch has smaller conduction pressure, the switch can be conduced by slight pressure.

Description

technical field [0001] The invention relates to electronics and switches, in particular to a pressure-sensitive interactive pen in a visual interactive projection system, in particular to an omnidirectional light touch switch. Background technique [0002] Tact switches have been widely used in various electronic devices to control the switching operation of circuits. According to existing products and [0003] The working principle of the design can be roughly divided into two types: direct pressure type and side pressure type. [0004] Direct pressure type: prevent a metal shrapnel under the touch button, through pressure, make the shrapnel contact with the bottom electrode, and the circuit conducts. This kind of product can only withstand positive pressure, and its conduction force depends on the elasticity of the shrapnel, generally above 100 grams. [0005] Side pressure type: By preventing multiple electrode contacts at the bottom of the shrapnel, multi-directional c...
