Compact, dependable latching on/off control for panels and projects — 1PC Blue Self locking 16MM Latching Push Button Switch No lighting 2Pin R16503 Why choose this switch Simple, reliable on/off control: The selflocking (latching) mechanism keeps the switch in the pressed or released position until you press it again, avoiding the need to hold the button and preventing accidental state changes. Clean, lowcomplexity design: No builtin lighting keeps wiring and installation straightforward and avoids the need for extra power or LED components. Easy to integrate: Twopin wiring and a compact 16MM size make this switch well suited for a wide range of panels and small devices. Key attributes Model: R16503 Quantity: 1PC Color: Blue Action: Selflocking / latching (pushon, pushoff) Size: 16MM (panel mounting footprint) Lighting: No lighting / nonilluminated Pins: 2pin configuration for simple wiring How it solves common problems Eliminates accidental toggles by holding its state until intentionally changed, which is useful where consistent on/off status is important. Reduces installation complexity by providing a nonilluminated option when indicator lighting is not required or would add unnecessary cost or power consumption. Fits small or crowded control panels where a 16MM mounting hole and a compact footprint are needed. Typical applications Control panels and instrument clusters: Use as a reliable on/off control for functions that require simple manual latching without illumination. DIY electronics and hobby projects: Simple twopin wiring and a compact 16MM form factor make it suitable for hobby enclosures, custom controllers, and retrofits. Small appliances and power control modules: Use where a durable mechanical latching switch is required and indicator lighting is unnecessary. Installation notes Designed for a 16MM panel cutout and twowire connections. Check panel thickness and mounting method to ensure a snug fit. Connect the two pins according to your circuit needs; this is a nonilluminated switch, so no separate LED wiring is required.
