Waist-shaped (oval) metaldome5.0mmx3.7mm nickel-plated domes

Nickel-plated waist-shaped metal dome with 5 contact points and dust-proof switch.

Product Characteristics

Tactile metal domes are momentary switch contacts that become normally open switches when used with a printed circuit board, flex circuit, or membrane. They are placed on printed circuit boards through pressure-sensitive adhesive tape, captured in a pocket design。
