Examples relate to a compressible housing. An electronic switch may include a circuit board. A first conductive surface may be coupled to the circuit board and a second conductive surface may be located proximate to the first conductive surface. A compressible spacer may be located between the first conductive surface and the second conductive surface to space the first conductive surface away from the second conductive surface. Further, a compressible housing may deform when under compression and may cause, via deformation of the compressible spacer, the first conductive surface to contact the second conductive surface.

A sealed button assembly including a button cap, a push rod, a button retainer, and a bracket is described. The bracket can couple to the button retainer which itself can interlock with the button cap and push rod through a counterbore, the counterbore being defined in a sidewall of the housing of an electronic device.

A pedestrian pushbutton for activating a traffic device. A plunger mounted in a housing impinges on a piezo element when pressed. O-rings between the bolts that secure the plunger to the housing and the housing bias the plunger inwardly. A foam disk under the piezo element, or a resilient stem bumper on the back of the plunger, or both, bias the plunger outwardly with a force about equal to the inwardly biasing force of the O-rings on the bolts. Thus, the opposing resilient members maintain the plunger at neutral buoyancy when at rest. An O-ring disposed between the edge of the plunger and the opening in the housing centers the plunger. The pushbutton may include light and sound assemblies to confirm to the pedestrian visually and audibly that the pushbutton has been engaged. The sound chamber may be tuned based on the Helmholtz formula to achieve an optimum frequency.
