A cartridge type pressure switch is formed with a cup-shaped contact flanged outwardly at its rim and slidably nested in an annular spacer. A flexible diaphragm has an integrally formed annular bead ring which is stretched over the spacer to secure the diaphragm in place over the cup-shaped contact. A spring nested in the cup-shaped contact has the outer end registered against a deck or spring retainer. A pair of stationary contacts on opposite sides of the spacer have terminal portions extending outwardly through the deck. The spring biases the cup-shaped contact in a direction to seat the flange against the stationary contacts. When the cartridge is inserted in a bore, the bead ring is compressed to seal the cartridge in the bore. When a plurality of cartridges are received in bores in a block or manifold, a spacer and lead frame are commonly received over the terminal portions of the contacts on each cartridge for providing electrical connection; and, a cover is received over the lead frame and attached to the block. Alternatively a single cartridge is inserted in a bore and retained by a plate, with terminal pins connected to cut outs in the terminal portions of the contacts.
