The Delock Rotary Switch for Panel Installation 22 mm 3 x Solder Terminal with Twist Protection is compared against the alternative models Delock Emergency Stop Button 22 mm Latching Stainless Steel 3 x Solder Connection MPN 22148 and Delock Emergency Stop Panel Mount Switch 19 mm 3 x Solder Connection Stainless Steel Latching. All products are panel-mount control components from the same manufacturer featuring three solder connections, but they serve fundamentally different functional purposes: the rotary switch is designed for routine manual operation in custom electronics, whereas the alternative devices function as latching emergency stop buttons.
⚙️ The table below compares the key technical specifications and design features, including mounting diameter, operation mechanism, and housing materials.
| Feature | Delock Rotary Switch 22 mm | Delock Emergency Stop 22 mm | Delock Emergency Stop 19 mm | Practical Significance |
|---|
| Device Type | Rotary switch | Emergency stop button | Emergency stop button | The rotary switch provides routine control and setting adjustments, while emergency stop buttons are dedicated safety devices for shutting down equipment. |
| Mounting Diameter | 22 mm | 22 mm | 19 mm | The 22 mm models fit standard cutouts and share installation dimensions, while the 19 mm version is better suited for space-constrained control panels. |
| Mechanism | Rotary | Latching | Latching | The rotary switch allows flexible multi-position control, whereas the latching mechanism on the emergency buttons locks down upon pressing and requires manual reset. |
| Housing Material | Standard panel-mount build | Stainless steel | Stainless steel | Stainless steel versions offer enhanced durability and resilience in demanding industrial environments. |
| Connection | 3 solder terminals | 3 solder connections | 3 solder connections | All three devices feature a consistent three-terminal solder connection layout for secure and reliable wiring. |
◎ The use-case table below helps determine which product is most suitable for specific application needs and installation requirements.
| Use case | Recommended product | Why |
|---|
| Building custom control panels and bespoke electronics | Delock Rotary Switch for Panel Installation 22 mm | Provides a convenient manual interface for routine switching and functional control. |
| Industrial automation systems requiring safety shut-off (22 mm cutout) | Delock Emergency Stop Button 22 mm Latching Stainless Steel | The stainless steel construction and latching mechanism ensure reliable emergency shutdown capabilities. |
| Compact enclosures with limited panel installation space | Delock Emergency Stop Panel Mount Switch 19 mm | The smaller 19 mm mounting diameter allows integration into tight spaces where standard cutouts do not fit. |
The Delock Rotary Switch for Panel Installation 22 mm 3 x Solder Terminal with Twist Protection is best suited for applications requiring regular manual control and switching, unlike the emergency stop alternatives built for safety shut-off functions. Choose the main product if you need a dependable rotary control element for custom electronics, and opt for the stainless steel latching alternatives when safety and emergency stopping are your primary requirements.
