Low pressure switch tablock

The utility model discloses a low pressure switch tablock relates to switch annex field, mismatches to present tablock and partial low pressure switch length, and the tablock of can only buckling during the installation, calorific capacity is bigger down at equal operating current for the back tablock of buckling, and operating temperature is higher, easily scaling loss tablock and switch base, tablock bolt -up department opening is too big, easily leads to the perk of opening part tablock to lead to area of contact to reduce when screwing up the nut, the contact resistance increase, and calorific capacity rises suddenly to and because vertical opening is long groove -shaped, and the tablock reduces with switch area of contact, the scheduling problem that generates heat easily adopts the first connector of offering in tablock body one end and offers the second connector at the tablock body other end, and first connector is the through -hole, the second connector is the mode of long groove -shaped structure, a
