They are:
- TS03 (left of picture)
6x6mm, 5-9.5mm actuator, 160 – 260g force, through-hole - TS05
6×6 mm, 4.3-8mm actuator, 100-260g force, surface-mount - TS08 (right of picture)
6x6mm, 4.3mm actuator, 160g force, surface-mount - TS19
3x2mm, 0.6mm actuator, 70-240g force, surface-mount
All are SPST (single-pole single-throw), and some TS19 versions are rated up to 300,000 operations.
Operating is generally across -30 to 85°C, up to 12Vdc and up to 50mA, but check the data sheets for detail.
